Distinguish between core and linker nucleosomal DNA
What will be an ideal response?
Ans: Nucleosomal DNA is the length of DNA associated with a nucleosome, and averages a total length of about 200 bp. The core nucleosomal DNA has a length of 146 bp; it is directly associated with the histone octamer of the nucleosome and is more protected from nuclease digestion. The linker nucleosomal DNA, which varies in length from 8 to 114 bp, is less protected from nuclease digestion as it is more extended from the nucleosome.
